Structure for folding orchard tent for protection against train

ABSTRACT

An orchard tent folding structure comprises two frame sets and a shelter member having a plurality of tubular members and a plastic cloth. The frame sets comprise a rod member which is provided with a power source to drive the rod member to turn, a sprocket wheel and a slide wheel linked with the sprocket wheel by a chain member. The sprocket wheel turns along with the rod member. The chain member is formed of a chain section and a steel cable section. The shelter member is fastened at one side with the chain section, and at other side with a first steel cable and a second steel cable of the frame sets.

FIELD OF THE INVENTION

[0001] The present invention relates generally to a cultivation equipment of fruit trees, and more particularly to a structure for folding an orchard tent which is intended to provide the orchard with protection against the rain.

BACKGROUND OF THE INVENTION

[0002] The conventional way of growing the fruit trees is generally carried out in the open field without a shade for protection against the rain, which is often a culprit for various diseases of the fruit trees.

[0003] The use of pesticide or fungicide is a common practice for controlling the pathology of the fruit trees. However, in light of the pesticide or fungicide being harmful to the environment in which we live, the fruit farmers have a propensity to use as little pesticide or fungicide as possible. For this reason, an orchard tent is commonly used by the fruit farmers to provide fruit trees with protection against the rain, so as to minimize the pathological incident in the orchard. In addition, the orchard tent serves to reduce the frequency of spraying fungicide or pesticide in view of the fact that the fungicide or pesticide is apt to wash away by the rain. As a result of reduction in frequency and quantity of the pesticide or fungicide that is sprayed , there will be less residue of the pesticide or fungicide on the fruit.

[0004] The conventional orchard tent must be erected on site. The erection of the conventional orchard tent is rather time-consuming.

[0005] This inventor of the present invention discloses in the People's Republic of China utility model Patent No.ZL 00217491.X an orchard tent which is intended to provide protection against the rain. However, the orchard tent so disclosed also works to shield the sunlight which is essential to the photosynthesis of fruit trees. As a result, the orchard tent must be rolled up on a sunny day, so as to enable the fruit trees in the orchard to be exposed to the sunlight. The orchard tent is rather cumbersome and is set up at a considerable height, thereby making it difficult to be folded manually.

SUMMARY OF THE INVENTION

[0006] The primary objective of the present invention is to provide an orchard tent with a folding structure to facilitate the folding of the orchard tent that is erected in the orchard to provide fruit trees with protection against the rain.

[0007] The features, functions, and advantages of the present invention will be readily understood upon a thoughtful deliberation of the following detailed description of two preferred embodiments of the present invention with reference to the accompanying drawings.

[0012]FIG. 6 shows a perspective view of a second preferred embodiment of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] As shown in FIGS. 1-5, an orchard tent folding structure of the first preferred embodiment of the present invention comprises the component parts which are described hereinafter.

[0014] Two frame sets 10 comprise a first support 11 and a second support 12 separated from the first support 11 by a predetermined distance. A first steel cable 13 is mounted on the top of one side of the first and the second supports 11 and 12. A second steel cable 14 is mounted on other side of the first and the second supports 11 and 12 such that the second steel cable 14 is parallel to the first steel cable 13.

[0015] A shelter member 20 comprises a predetermined number of tubular members 21 and a transparent plastic cloth 22. The tubular members 21 are provided in the underside with a notch extending along the longitudinal direction thereof. The transparent plastic cloth 22 is spread out by means of a plurality of soft plastic bars which are inserted into the notches of the tubular members 21. Each tubular member 21 is provided on the top of two longitudinal ends thereof with a safety hook 23. The safety hooks 23 of the shelter member 20 catch the steel cables 13 and 14 before the plastic cloth 20 is completely spread out.

[0016] A rod member 30 is pivoted at both ends to the inner side of the top segment of the first support 11 and is provided at the midsegment with a power source 31, which is a motor, for driving the rod member 30 to turn at a predetermined revolution.

[0017] Two sprocket wheels 40 are respectively mounted on two outer ends of the rod member 30 such that the sprocket wheels 40 turn along with the rod member 30.

[0018] Two slide wheels 50 are respectively pivoted to the inner side of the top segment of two sides of the second support 12 such that the two slide wheels 50 are corresponding in location to the two sprocket wheels 40.

[0019] Two chain members 60 are endless. The chain members 60 are engaged with the sprocket wheel 40 and run through the slide wheel 50. The chain members 60 have a chain section 61 and a steel cable section 62. The chain section 61 extends rightwards toward the sprocket wheel 40 from the proximity of the bottom edge of the slide wheel 50 such that the chain section 61 is completely engaged with the sprocket wheel 40.

[0020] The left side of the shelter member 20 is fastened with the left end of the chain section 61. The front and the rear ends of the right side of the shelter member 20 are respectively fastened with the first steel cable 13 and the right end of the second steel cable 14.

[0021] On a sunny day, the power source 31 is started to actuate the rod member 30 to rotate in a counterclockwise direction indicated by and arrow 100 as shown in FIG. 4. As a result, the chain section 61 of the chain member 60 is pulled rightwards by the sprocket wheel 40. As the shelter member 20 is in the unfolded state, the left side of the shelter member 20 is fastened with the left end of the chain section 61 of the chain member 60. As a result, the shelter member 20 moves rightwards at an appropriate speed along with the chain section 61 such that the shelter member 20 is completely pulled to the right end as shown in FIG.5. On a rainy day, the power source 31 is started to actuate the rod member 30 to rotate in a clockwise direction, so as to pull the shelter member 20 back to be in the unfolded state as shown in FIG. 4.

[0022] The power source 31 of the present invention may be controlled by a remote control device.

[0023] As shown in FIG. 6, an orchard tent folding structure of the second preferred embodiment of the present invention is different from the first preferred embodiment of the present invention in design in that the former comprises a plurality of arcuate tubular members 21, which enable the plastic cloth 22 to spread out to shape like an arch. In order to facilitate the folding of the orchart tent, the shelter member 20 of the second preferred embodiment of the present invention is provided at the center of the top thereof with a third steel cable 15. In the meantime, each tubular member 21 is provided at the center of the top thereof with a safety hook for catching the third steel cable 15. In addition, the first support 11 is provided in the inner side of the midsegment thereof with an upper sprocket wheel 70. The second support 12 is provided in the inner side with an upper slide wheel 80 opposite to the upper sprocket wheel 70. The upper sprocket wheel 70 and the upper slide wheel 80 are linked by a chain member 90. As the power source 31 is started, both the rod member 30 and the upper sprocket wheel 70 are actuated to turn.

[0024] The chain member 90 also has a chain section 91 and a steel cable section 92.
